What is the difference between do while and do until loop in vb programming?

Answer 1

Do while and Do until are interchangeable, and they take the opposite condition.

Do While executed the body of the loop while (condition=true), and Do until executes body of loop until (condition=true).

For example, if I was doing a Loop to say, while the check box is checked, display a message box (Never do this btw, it's just an example)

I could either say

Do While (MyCheckBox.Checked = True)

Loop

or

Do Until (MyCheckBox.Checked <> True)

Loop
